Python之小试牛刀(一)-上证K线和估值

      做为一个C或C++的底层程序员其实极其少去用JAVA和Python这两名语言的，怎么说呢，我感觉用这两种语言写出来的程序还是有点吃内存的，嵌入式程序写得多的人，对资源消耗特别敏感，所以我一直都很少用它们写程序。不过这几天也是太闲，被一玩基金的哥们天天安利说很好，可以算股票基金估值，爬网上数据，一时心血来潮，要不试试(笔者也买点基金，竟然被说动了，真有点打脸)，三下五除二，胜在代码真的简单，巴拉巴拉几下，就成了，竟然真出来拿Python写代码来爬数据了，虽然结果速度不敢恭维，不过也当学习一下金融和技术知识了！这次的学习，其实就是扒拉扒拉某软件的股票K线数据，Python代码以前基本没写过，但自学过一个星期，反正环境以前也安装过，感觉写代码真的很快，前后不到30分就整成了一个带Windows界面的趋势线，能明显看到目前10几年前的指数点位变化。试着玩一把，学习Python以来的第一个Python程序嘛，讲究就是能用即可！

      失业这么多天了，除了找工作，天天学习硬件知识，就是无聊写点代码玩玩！算是自娱自乐吧！（图片属于自娱自乐，不提供参考）
